Problem Statement

If in the formula C \equal{} \frac {en}{R\plus{}nr}, nn is increased while e e, RR and rr are kept constant, then CC:
<spanclass=′latex−bold′>(A)</span> Increases<spanclass=′latex−bold′>(B)</span> Decreases<spanclass=′latex−bold′>(C)</span> Remains constant<spanclass=′latex−bold′>(D)</span> Increases and then decreases<spanclass=′latex−bold′>(E)</span> Decreases and then increases<span class='latex-bold'>(A)</span>\ \text{Increases} \qquad <span class='latex-bold'>(B)</span>\ \text{Decreases} \qquad <span class='latex-bold'>(C)</span>\ \text{Remains constant} \qquad <span class='latex-bold'>(D)</span>\ \text{Increases and then decreases} \qquad\\ <span class='latex-bold'>(E)</span>\ \text{Decreases and then increases}
